Alright guys I installed my edge evolution cts Saturday on my 2001 f150 everything went great set it to the 2 level towing setting and it was going great. Today I headed to work and bout a mile unto it I gave it gas and it had no go at all it got up to twenty or so and finally had some get up. The only setting I changed was speed limiter and tire size any ideas on what might be wrong?

 

No thoughts at all. Were there any codes?

If the problem happens again, return the tune to stock and see if you still have the problem. If it does, you have a problem in the basic vehicle that you'll have to track down and fix. (Plugs, coils, fuel filter, throttle body are some of the likely culprits.) A "tune" can exaggerate a basic vehicle problem, because the previous "learned" behavior is wiped out and the PCM can't really relearn fast enough.

If the problem only occurs at the level 2 tune though, you need to get help from Edge Tech Support.

Mine did the same thing as I did the same exact thing you did. I pulled into a parking lot and set the Rev limiter and tire size both back to normal. Speedo is slightly off but no more problems

 

I'll def try that its throwing ten codes ill write them down and up load to here if it doesn't fix the problem ill be back thanks guys

 

OK, this post is directed to 405:

Try setting your Tire Size back to the value you had it at when your speedo was correct. If the problem does not return, it sounds like it was associated with the "rev limit" setting. What value did you have set in there?

Again though, this is really starting to sound like a fault in the code in the Edge. I'd talk to Edge Tech Support about it. I know they recently published a firmware update - I'm thinking there was an unfortunate "side effect" to that update they are not aware of.

Alright guys I guess I bashed edge a lil too early....turns out I had a short in some wiring which in turn screwed my truck bad.....thank the good Lord above I didnt have to ship it to Ford.

 

Thank YOU for letting us know this. many people would not have bothered, which does the forum a great disservice.

I'm really glad you found the problem, too. Can you describe the wiring fault?

I'll have some time to try it out again this weekend, I just got the pod from UPS today and I'll put it together and post again. The factory Rev was @ 5200 rpm and I set it to 5000. Changed the tires from factory to larger tire. I just remember it acting up so I just put it back to stock.

I am also curious about the shift points you can program in. I wish that my truck would shift at a lower RPM instead of just wringing it out. I saw were i could set the MPH to shift but there will be times that I would want to drive smoother and shift sooner.

It seems that Edge has the color codes down for their pods now. Mine is flint gray and matches the dash color perfectly.

I have sent several emails to Edge and never got a response. Waiting on the phone seems like forever. You can leave a message and they will return your call but its at a time when you aren't near the programmer. I may try to clear things up on here if someone is willing to assist.

Appreciate the response!

 

Happy to respond.

First - if you have the rev limit set at 5000 or 5200, that's too low. Raise it to at least 5400. Mine's at 5600. This is not an RPM you're going to "drive" at, it's just a limit where the PCM is going to stop giving the engine gas or spark (or both) to prevent damage.

Second - You can't change the WOT shift points with the CS/CTS at this time. Supposedly, Edge is working on this and you will be able to in the future. They CAN be changed with the older Evolutions. I suspect Edge has placed them at a reasonable point, if you have the rev limit set up as I said in the earlier paragraph.

Third - It sounds like you are looking for the "normal" shift points that I prefer. These are the "part throttle" upshift/downshift and torque converter unlock/lockup points. There are 14 settings here. I reduced my 1-2, 2-3, and 3-4 upshift/downshift settings by the max: -2, -3, and -5 as I recall. Then, I reduced my TC unlock/lock values for 1st, 2nd, 3rd and 4th gears by the max again: -2, -3, -5, and -10.

My whole goal was to get the truck in the highest gear as soon as possible with the TC locked up under normal acceleration and, to keep it there as long as possible under mild engine load (climbing gentle hills, etc.). These settings have no effect on WOT acceleration maneuvers like passing. But, they inhibit what was to me an annoying tendency of the truck to downshift when it didn't seem necessary, and to maybe save gas by getting it into overdrive quickly.

Realize though, that the part throttle shift and TC lock/unlock points are a function of BOTH speed AND throttle position (load). A heavier foot will move these points to a higher speed and vice-versa.

Does what I'm saying make sense here?

Well what happened was that down here in NC we had some snow so I kicked the 4wd in yesterday morning well turns out the wiring on the O2 sensor was rubbing the drive so when the 4wheel was engaged it rubbed through the wiring and caused the truck to short out. It keep blowing fuses finally we traced it down re taped it and completly zip tied it up, now she runs like a dream

 

Yes it makes sense. How is the Edge able to correct the speedometer? is it in the transmission or is it the infamous speed sensor that is located in the rear end?

 

There is a sensor, possibly in different locations depending on your model year. But, if the Edge (or any other programmer) can correct the speed, it's because it changes the code in the PCM that interprets the revolution count of that sensor and changes those revolutions to a distance traveled. Divide that by time, and you've got a "speed".

If you have bigger tires, each revolution has to be seen as a longer distance traveled, and vice-versa.

Earlier PCM's did not have coding to change the distance per revolution, so the sensor itself had to be changed.
